Y --Be it known that L-Iano Bveonffnasn, a

citizen of the United States ofy America, residing at Detroit, in thecounty ofjVVayne and `State of'Michigamhave invented ce1'- tain new andusefulImprovements inf Submarine-Protecting'Devices, of which the1following is ay speciication, reference being had .vt-herein to theaccompanyingdrawings.

vThis invention relates vtosubmarine nets,

Vand has special reference to nets or similar protecting devices adaptedtofbeicarried by vessels. Y

J-Theprimary objectj my invention is tol kfurnish sea-going boats withnets fori 'protect- 'inggdevices that may beraised and lowered,

so that'J the nets may'fbe placed in inactive Vpositions when'in safewaters lthus' :allowing the vessel Yto lmake speed,l and; lowered to ac-2o tive v.position when passingl through Ya danger zione7 tofrprotectthe sidesof the vessel from v'torpedo-and submarine attack. .Y

A'further object of my inventionis to provide outriggers for-the nets orprotectingdevices, and simple,pdurable and-'efficient means isl'employed'V 'for simultaneously adjusting theoutriggers andn'ets.

"The above andother objects are attained 'f by a mechanical construction:that vwill be hereinafter specifically described and then claimed, andreference'willnowbe had to the. drawings, wherein Figure 1 is aperspective view ofa vessel provided with the nets or protecting devicesY and showing the same in active position;

Fig. 2 is a perspective view of one of the outriggers and its net; v

Fig. 3 is a front elevation of the net with part of the Outrigger brokenaway, and

Fig. 4 is a detail perspective view of a.V

portion of a net and its'carrler. n Y Y In describing my invention byaid of the views above referred to, I desire to point out Y that thesame are intended as merely illus- Y trative of one way in which myinvention may be put into practice, and I do not care to confine myselfto the precise construction and arrangement of parts shown. Thefollowing description is therefore to be broadly construed as includingsuch substitutecono struetions and arrangement of parts which ofbrackets or bearings 1 and pivotally conare the kobvious equivalent ofthose toV be hereinafter referred to.

To put my invention into practice, I provide the gunwale or side of avessel with sets .specification @stette-'s ment. patented nebeaaiiaie.Application vfledlvecemberl?,1917; Serial No; A207,471.`

neeted thereto isfan Outrigger' frame. 2 having parallel side rails-3that are preferably made of channell bars with the opensides 'thereofconfronting, so as to receiveflanged members'for wheels e re-volvabie onaxles 5 v mounted in the ends ofa carrier 6. Thefcarrierl 6 mayrl beconstructed' of channel meinbers and angle braces,v as best vshown invAt'the 'outer' end ofthe carrierGai-e A hangers 7 fora -net orprotectimgv device 8,

ous implement of, war directed at the vessel. vThe side of' thevessel,intermediate the `brackets vor bearings l, `is provided with astanchionl() having sheaves 11 at vthe upperV end thereof androtataiblespools or drums 12 and 13" adjacent the lower end thereof. lThe spools4or drums-12and 13 rot-ate together and are similar to anordina'ryhoisting drum adapted to -beeasily operated byv a f cra-nk' 1e or from adonkey engine; or other source of power. Attached to the drum 13 andadapty edvto be wound thereon isla cable 19 extending overone of thesheaves `11 and having branch p ortionsl` connected tortheouter end ofthev Outrigger frame2, said cable being employed for raisingy theoutrigger frame from an active position, such as shown in Fig. 1, to aninactive position, as shown in Fig. 2. Y

Attached to the drum 13 and adapted to be wound and unwound thereon is acable 17 extending upwardly over another of the i sheaves 11l and saidcable forms part of a block and tackle 18 connecting the innermost aXle5 and the side of a vessel, so that the carrier may be pulled inwardlyon the outrigger frame to an inactive position.

Attached to and adapted to be wound and unwoundonvthe drum 12 is anothercable 15 and this cable forms part of a block and tackle 2O connectingthe outer end of the Outrigger frame 2 to the outermost axle 5,

, so that the carrier may be shifted to the outer end of the Outriggerframe 2 and placed in an active position. The manner of attaching theycables 15, 17 and 19 to the drums12 and 13 and winding and unwinding thesame thereon is such that when the Outrigger frame is raised to aninactive position the carrier will be drawnV inwardly, also l. yinlowered positions, tend into the Water that When the Outrigger frame 2islowered to an active position, the carrier will be shifted to theouter end thereof. A'

On the Outer end of the Outrigger `frame 2 and at one end thereof is abracket 21 and a guide 22, the latter being for a pin 23 connected to abell crank 24: carriedlby the bracket 21. The pin 23 is held normally inan extended position by a coiled retractile spring 25 connecting thebell crank 24 to the guide 22 and said pin is adapted to enter anopening 26 in the side of the'net or protecting device 8 and lock thesaine in a vertical position substantially at a right angle to theOutrigger frame 2.

A cable or cord 27 it attached to the bell crank 24 so that. the pin2B'm'ay be retracted when it is desired to raise `the Outrigger frameand swing said frame and the net to an inactive position. A p

By reference to Fig. 1, ity will be noted that the sides of the vesselare provided Witli a plurality of the nets or protecting devices sothatpractically the entire sides Vof the vvessel Will be protectedagainsttorpedo attack. When the nets or protecting devices are for asufficient depth to protect the hull ofthe vessel and as all or' thenets or devices longitudinally aliney at each side .of the vvessel,there is a minimum l of resistance to therprogress of the vessel,

and after passing through danger Zones, the nets` or protecting devicesmay be raised so that the vessel may 'make speed.V

What Iclaim is Y 1. Aprotecting device prising an Outrigger frameadapted to be pivotally connected to the side of a vessel,

a carrier movable longitudinally `of said said nets or devices eX- forvessels, c'om-V Y Outrigger, a net suspended from the outer end of saidcarrier, means connected to said carrier and said Outrigger frameadapted for raising and lowering `said OutriggerV frame and shiftingsaid carrier longitudinally thereof, and means at the outer end vof saidOutrigger frame adapted Vfor locking said net in `an active positionrelativelyV to Y said Outrigger frame.

2. The combination with a vessel, of a stanchion at the side thereof, anOutrigger sel, a carrier movable longitudinally ofsaid protecting devicesuspended Outrigger,` a from the outer end of said carrier, meansconnected to said carrier, thejside of "said vessel and said Outriggerand-.operatable at said .stanchion adapted for simultaneously yadjustingsaid Outrigger 'and shifting said carrier ,longitudinally thereof, andmeans operatable at the side of the vessel and at the Outer end of theOutrigger adapted for locking said carrier and its protecting ldevice inan active position. 1 f In testimony whereof l afIiXv myV signature inthe presence of two Witnesses.
